flyctl

flyctl is a command-line interface for fly.io

Note: Most installations of flyctl also alias flyctl to fly as a command name and this will become the default name in the future. During the transition, note that where you see flyctl as a command it can be replaced with fly.

Getting Started

1. Sign into your fly account

fly auth login

2. List your apps

fly apps list

2. View app status

fly status -a {app-name}

App Settings

flyctl will attempt to use the app name from a fly.toml file in the current directory. For example, if the current directory contains this file:

$ cat fly.toml
app: banana

flyctl will operate against the banana app unless overridden by the -a flag or other app name setting in the command line.

Releases

flyctl is automatically released at 3 PM Eastern Standard Time Monday - Thursday. If needed, you can bump a release by running ./scripts/bump_version.sh.

Building on Windows

There is a simple Powershell script, winbuild.ps1, which will run the code generation for the help files, format them, and run a full build, leaving a new binary in the bin directory.

Running from branches on your local machine

Run scripts/build-dfly to build a Docker image from the current branch. Then, use scripts/dfly to run it. This assumes you are already authenticated to Fly in your local environment.
